18 Claims.

This invention relates to lagging for reels used for storing andtransporting heavy material,

such as lead covered cable, particularly to lagging provided with meanswhereby it may be secured upon such reels.

Objects of the present invention are the provision of an improvedconstruction for reel lagging having a low weight consistent with therequired structural strength and simple and practical securing meanswhereby it may be readily andefiectively secured to reels and easilyremoved therefrom.

In accordance with the above objects, the invention in-one embodimentthereof comprises a plurality of segmental shaped sheet metal lags forenclosing a metal reel which includes annular head rims upon which thelags are placed side by side. Each lag comprises a plurality of integralchannel-like formations terminating in 20 radially extending end arms,the formations having welded thereto reinforcing side walls extendingfrom the outer peripheral channel walls inwardly toward the outersurfaces of inner walls interconnecting and extending from the side armsof the channel formations, the latter walls bearing upon the head rims.The lags are provided with means adjacent the inner edges of the headrims to prevent substantial longitudinal movement of the lags on thereel. Formed in. the opposite side edges of each of the channel sidearms and the end arms adjacent the outer surfaces of the interconnectingwalls and the inner edges of the reinforcing side walls of the lags anda filler or sealing lag are slots for the reception of a 35 retainingmember which encircles the rims under tension for securing the laggingupon the reel.

Means secured to eachof the head rims at diametrically opposite pointsserves to effectively preventthe accidental displacement of the mem- 40her out of the slots.

Other objects and advantages of this invention will more fully appearfrom the following detailed description, taken in connection with theaccompanying drawings, in which:

Fig. ,8 is a further modifiedform of lagging and means for securinglagging upon a .reel,.and

Fig. 9 is a fragmentary vertical section taken on the line 9-9 of Fig.8'.

Referring now to the drawings, and particularly to Figs. 1 and 2, oneform of lagging em-' bodying the invention is illustrated, for example,in conjunction with acable reel comprisinga pair of spaced headslainterconnected by a drum [I (Fig. l.) for holdinga leadcovered cablei2, (Figs. .2 -and l) orother heavy material that may be wound thereon.The cable reel itself may beof any suitable construction,although awelded allmetal constructionis preferred. In the constructionillustrated, the heads each comprisean outer annular rim it concentricwith the drum H and a plurality of corrugated plates of segmental shapewelded together to forman annular head plate 55 and welded at its innerand outer peripheries'to the drum ll and outer annular rim M,respectively.

One form of lagging embodying the invention comprises .a plurality ofsegmental shapedlags it (Figs. v2 and 4) of uniform size andconstruction andsufficient in number so that whenplaced side by side onthe rims Hi and across the widthof the reel, as shown in Figs. 1 and 2,a covering or enclosure is provided for the cable storage space of thereel except for a peripheral space which is less than the coveringprovided by one of the lags it which space is closed by a filler orsealing lag ll, which will be described presently.

Each lag 16 preferably comprises aplurality of integral channel-likeformations 88 formed from a single sheet of metal with radiallyextending relatively short arms H9 at each end. Welded at their innersides to the edges of the channel-like formations 58 at. eachsidethereof is a reinforcing side wall member 2| which extends from oneend to the other of the lag to tie the channel formations l8 and endarms is together to form a rigid structure. The wall-members 2| extendfrom the outer peripheral edges of the channel web walls inwardly to apredetermined distance from the outer surfaces of walls 22 (Figs. 2 and3) interconnecting the channel formations I8 for a purpose which will bereferred to presently. The lag I6 is further strengthened intermediatethe side walls 2! by a member 23 which is T- shaped in cross-section,the member being welded to the spaced inner surfaces of the walls 22 andalso to end walls 2 3 (Fig. 5) from which the end arms I?) extendradially. Each end of the lag is further. strengthened by an invertedirregular shapedv member 25 (Fig. 5) U-shaped in crosssection' andarranged opposite the member 23 and welded along all of its edges to thesurfaces of the adjacent channel formation it and the end arm l9 and theend wall 2 extending between the arm and the channel formation.Struckout from the walls 22 interconnecting the channel formations it ofthe lag l6 adjacent the side walls 2! and arranged to extend over theinner edges of the head rims M are tabs 26 which serve to effectivelyprevent substantial longitudinal movement of the lags on the reel.

One embodiment of the improved means for securing the lagging of theabove described type to the reel head rims i4 comprises the following.At each side of the lag Hi the opposite side edges of the side arms ofthe channel formations l8 and the end arms K9 are slotted, as indicatedat 28 (Fig. 3), in the space provided between the outer surfaces of thewalls 22 and 2d interconnecting each of the channel formations-and theend arms and the inner edges of the side walls 2| for-the reception ofsteel retaining tapes or bands 29 which encircle the rims l4 and tie thelags under tension to the reel heads iii. The dimensions of the slots 28relative to that of the bands29 are such that the bands may be freelyentered into slots. To insure that the bands 29 will not accidentallymove out of the slots 28.

during movement and transportation of the reel, each reel head NJ hasbolted to the inner periph cry of its rim M at substantially oppositepoints a pair of L-shaped tape retaining clips 36. The clips are formedwith an arm 3! which extends over the outer edge of head rim M and theband 29, thus preventing outward movement of the band from its lagretaining position in the slots 28.

To secure the lags IE to the head rims It the reel is preferably mountedon a suitable device whereby it may be freely rotated during thesecuring of the lags. The first lag i6 is fixed to the pair of head rimsHi by aligning the apertures provided at opposite sides of the lag, forthe reception of the bolts used to retain the clips 33 in band retainingposition, with the Eorresponding apertures in the head rims, alsoprovided for the clip holding bolts; It is tobe understood that each ofthe lags i6 is provided with similar apertures although in the completedenclosure for the reel only two substantially opposite lags have theband retaining .clips 3i! attached thereto. Thereafter bolts are enteredin the aligned apertures and nuts are threaded onto the inner ends ofthe bolts. If found necessary additional clips 38 may be employed.

A temporary tie member or band may be suitably attached to the firstsecured lag i6 intermediate the head rims M drawn over the outerperiphery thereof and sufficient tension maintained in the band to holdthe following lags as they are placedin abutting relation around the "70peripheries of the head rims M as the reel is rotated. When a requisitemember of lags 16 has been placed in position to completely enclose thecable storage space of. the reel, except for the peripheral space to befilled in by the sealing lag 5 I! the temporary band is drawn up tightlyand suitably retained. The peripheral rim surfaces to be engaged by thelag ll serves to provide suitable spaces for sealing the ends 'of theretaining bands 29. The permanent tie member or band 29 is then insertedin the series of slots 28 provided in each of the lags H6 at each sidethereof and when the bands have been completely extended around the twoseries of slots they are drawn up tightly under a desired tension and asealing or tying member 32 (Fig. 4) is attached to the overlapping endsof each band extending across the peripheral rim surfaces to be engagedby the opposite ends of the lag H to maintain the applied tension, thuseffectively securing the lags I6 to the reel. Thereafter the temporarytie member is released and removed from the reel.

The sealing lag H (Figs. 4 and 6), previously mentioned, which is usedto fill in the space not occupied by the lags it comprises a singlechannel formation '35 reinforced and strengthened in a manner similar tothe lags l6 and provided with slots 36 at each side for the entrance ofthe retaining bands 29, the slots being similar tothe slots 28 of thelags 96 except that the slots 36 at one side, the side thereof which isfirst entered in the space between the first and last of the lags itmounted on the reel are twice as deep as the slots 36 at the oppositeside and the slots 28 of thelags it. To complete the enclosing of thereel the sealing lag H is slid into position in the space left betweenthe first and last lags l6, previously mounted on the reel, the side ofthe lag l1 having the deepest slots 38 being first moved into positionbetween the lags 16 across the head rims 'M from right to left ,asviewed in Fig. 2 and the tensioned retaining band '29 along with thesealing member 32 at the left side of the head rim is raised 01f the rimsufficiently to permit the band slots 36 of the lag. To lock the lag I!in position to prevent longitudinal movement thereof on the reel it isbolted at one side thereof as indicated by bolt apertures 3'! (Fig.6) tothe head rim. The band retaining clips 30 are then bolted to each headrim M at diametrically opposite sides which completes the enclosing ofthe reel.

In Fig. 7 there is shown a modified form of the means shown in detail inFig. 3 for securing the lagging upon the reel wherein each wall 40interconnecting spaced channel formations 4i of each lag 42 are formedat their outer sides with integral upturned short lips 43 extendingacross the space between side arms of each channel formation. The lips43 are in line with opposite side wall members 44 of the lags, the inneredges of the side Wall members being spaced a predetermined distancefrom the upper edges of the lips 43. Side edges of the side arms of eachchannel formation M are slotted, as indicated at 45, the slot extendingbetween the outer surface of the wall ti] and the inner edge of the sidewall member A l and for a suitable distance inwardly. Thus a steelretaining tape or band 46 may be entered through the continuous slotprovided between the opposed'edges: of the side wall member 44 and theupturned lips 3 and dropped onto the upper surfaces of the walls 40 andbehind the inner surfaces of the lips 43. After the bands ii; are inposition behind the series of lips l3'at each side of the reel they aredrawn up tightly under a desired tension and their ends sealed 'or tiedin a manner similar to that described hereinbefore in connection withthe other embodiment of securing means. parent that in the constructionshown in Fig. 7 the bands 46 will be effectively prevented from movingout of the slots 45 without the use of clips similar to the clips 30 ofFig. 3 or other retaining members by means of the lips 43 formedintegral with the lags.

Figs. 8 and 9 illustrate a still further embodiment of lagging and meansfor securing the lagging upon a reel, the lagging comprising a series oflags 50 and a filler lag 5| which may follow the general formation andconstruction of the lags l6 and Il shown in Figs. 1 to 6, inclusive.Outer peripheral curved web walls 52 of each channel formation 53 of thelag 50 are formed with a pair of depressions or embossments 54 p whichextend across the entire width of the walls 52 and are spaced a suitabledistance from each side of the lag, the series of embossments at eachside of the lag being aligned. The filler lag 5| is also formed withembossments 51 in its peripheral curved web wall 58 of its singlechannel formation 59, which are aligned with the embossments 54 of thelag 50. In each space between adjacent channel formations 53 and 59 ofthe lags 50 and 5| and centered with the embossments 54 and 5'! isfitted a formed up and welded box-like member 60 having its outersurface in the plane of the outer surface of the embossments 54 and 51and retained in position by welding to the side arms of the channelformations 53. At opposite ends of each of the lags 50 and 5| betweenradially extending short arms BI and the adjacent channel formations ofthe lags and aligned with the embossments 54 and 51 thereof are fittedformed up and welded box-like members 62 which are retained in positionby welding. Outer end walls 63 of the boxlike members 62 are formed toabut and lie in the plane of the short end arms 6| of the lags 50 and 5|in order that no appreciable space will occur between the ends of thelags.

In securing the lags 50 and 5| to the reel head rims M the methoddescribed in connection with the structure shown in Figs. 1 to 6,inclusive, may be generally employed except that a steel retaining tapeor band 64 is entered in each series of aligned embossments 54 and 51extending around the reel, the bands being drawn up tightly under adesired tension and a sealing or tying member 65 attached to theoverlapping ends of each band which effectively secures the lagging tothe reel. It will be apparent that the box-like members 6|) and 62 notonly serve to support the bands 54 across the spaces between theembossed channel formations 53 and 59 and the short arms 6|, thusproviding a continuous supporting surface around the periphery of thelagged reel, but also serve as strengthening or reinforcing means forthe lags. In the lag construction of Figs. 8 and 9 employing thebox-like members 62 the use of a U-shaped member 25, as in Figs. 1 to-'7, inclusive, is not necessary since the members 62 serve asstrengthening members for the ends of the lags. The embossments 54 and51 not only serve to prevent the securing bands 64 from shiftinglaterally on the periphery of the lagged reel, but also permit the bandsto lie slightly within the periphery of the lagged reel, therebyprotecting them from damage during rolling of the filled reel.

For preventing substantial longitudinal movement of the lags 50 on thereel, angle members It will be ap--' B8 are welded to walls '69interconnecting the channel formations 53, the angle members'being fixedadjacent reinforcing side Wall members 10 and arranged to extend overthe inner edges of the reel head rims M.

The reellag'ging and securing means therefor in theseveral embodimentsconstructed and arranged as above described provides a simple rigidstructure having a low Weight consistent with its strength and offeringa maximum resistance against impact stresses encountered in normalservice of a reel and the several embodiments of securing means permitsthe lags to be readily and effectively secured to the reel and easilyremoved therefrom.
